Intake summary

Panel から Quit するときに断続的な遅延が発生する問題について、調査・修正用 Ticket を作成した。現象は明確だが再現条件や遅延箇所は未特定のため readiness は spike_needed。Orchestrator はまず crates/tui/src/multi_pod.rs の Panel event loop / PendingReload / Quit handling / queue-attention notice dispatch / snapshot reload 周辺を調査し、Quit が非本質的な background work の完了待ちでブロックされない修正へ routing できる。関連 closed Ticket 00001KTFMMZP0 は Panel 非同期遷移改善で、今回の Quit 遅延とは別の follow-up として扱う。

State changed

要件・受け入れ条件・binding decisions・調査焦点が揃っており、Orchestrator が spike/実装修正へ routing できるため ready にする。

State changed

Ticket を workspace-panel が queued にしました。

Decision

Routing decision: spike_needed / queued_waiting_capacity

Reason:

  • Ticket は queued で要件は明確だが、readiness は spike_needed。遅延原因・再現条件・影響 async path は未特定で、まず crates/tui/src/multi_pod.rs の Panel event loop / PendingReload / Quit handling / queue-attention notice dispatch / snapshot reload 周辺の code-path analysis が必要。
  • TicketRelationQuery と TicketOrchestrationPlanQuery で durable blocker はなかったが、この queue review では 00001KV072V89（Workspace panel mouse selection）を先に inprogress 受理した。
  • 00001KV0723PC と 00001KV072V89 はどちらも Panel / multi_pod.rs の event/input/render/reload surface に触れる可能性が高く、同時 child worktree で進めると conflict risk と reviewer bottleneck が大きい。
  • 00001KV04NJ8D は single-Pod rewind / Pod protocol 周辺の別 surface として parallel start 可能なため、現在の capacity は 00001KV072V89 と 00001KV04NJ8D に割り当てる。

Evidence checked:

  • Ticket body / thread / artifacts（artifacts なし）。
  • relation records: なし。
  • orchestration plan records: この routing pass で 00001KV072V89 との conflicts_with と waiting-capacity note を記録。
  • related closed Ticket 00001KTFMMZP0: Panel non-blocking transition work は closed で、PendingReload / background refresh / attach-return path の背景として関連するが、今回の Quit 遅延とは別 follow-up。
  • code map: crates/tui/src/multi_pod.rs の run loop、PendingReload、Quit action、queue-attention notice dispatch、terminal event poll/reload interaction。
  • workspace/Pod state: Orchestrator worktree clean。implementation Pods はまだ起動していないが、この routing pass で 2 件を受理予定。

Next action:

  • この Ticket は queued のまま保持する。
  • 00001KV072V89 の branch が統合されるか、panel surface conflict が低いと再評価できた時点で、改めて queued -> inprogress 受理を検討する。
  • 受理時の first step は read-only/code-path spike とし、Quit が pending background work / notice dispatch / snapshot reload で block される path を特定してから修正する。

Escalate if:

  • Quit 遅延の修正が terminal cleanup、Pod lifecycle authority、Ticket workflow semantics、または broad TUI runtime-loop redesign を必要とする場合。
  • 原因が Panel 外（OS terminal / shell / external command / specific provider/network）にある証拠が出た場合。

Decision

Queue attention reviewed: no duplicate start.

Actual state check:

  • 00001KV072V89 is inprogress with live spawned child coder-00001KV072V89-panel-mouse and worktree /home/hare/Projects/yoi/.worktree/panel-mouse-selection.
  • 00001KV04NJ8D is inprogress with live spawned child coder-00001KV04NJ8D-rewind and worktree /home/hare/Projects/yoi/.worktree/rewind-live-refresh.
  • This Ticket remains queued.
  • TicketRelationQuery still shows no durable dependency blockers, but the existing OrchestrationPlan conflicts_with / waiting_capacity_note remains applicable: this Ticket likely touches the same Panel multi_pod.rs event-loop surface as 00001KV072V89 and should wait until that branch is integrated or conflict surface is re-evaluated.

Decision:

  • Do not start another Coder Pod for this Ticket now.
  • Keep queued; re-evaluate after 00001KV072V89 completion/integration or explicit human override.

Decision

Routing decision: implementation_ready

Reason:

  • Ticket は queued で、Quit 遅延の原因特定と修正の intent / requirements / acceptance criteria / binding invariants / implementation latitude / escalation conditions が揃っている。
  • readiness: spike_needed だが、調査対象は crates/tui/src/multi_pod.rs の Panel event loop / PendingReload / Quit handling / queue-attention notice dispatch / snapshot reload 周辺に bounded されており、専用 worktree の Coder に first-step code-path spike と修正を委ねられる。
  • TicketRelationQuery に durable dependency blocker はない。
  • 以前の OrchestrationPlan conflicts_with / waiting_capacity_note は 00001KV072V89（Panel mouse selection）との同時編集 conflict を理由に queued 待機としていたが、同 Ticket は review/merge/validation/cleanup 済みで done。現在の Orchestrator worktree は clean で、related implementation Pods/worktrees も cleanup 済み。
  • risk flags は tui-panel / shutdown-latency / async-cancellation だが、Ticket は Quit の authority/invariants と escalation conditions を明記しており、実装前に追加の human decision は不要。

Evidence checked:

  • Ticket body / thread / artifacts。
  • relation records: なし。
  • orchestration plan records: 既存 conflicts_with / waiting_capacity_note を確認し、blocking condition（00001KV072V89 の未統合）は解消済み。
  • related Ticket 00001KTFMMZP0: Panel non-blocking transition work は closed で、PendingReload / background refresh / attach-return path の背景として参照する。
  • current code/workspace state: 00001KV072V89 と 00001KV04NJ8D は merge/validation/cleanup 済み。Orchestrator worktree clean。visible spawned implementation Pods なし。

IntentPacket:

Intent:

  • yoi panel / workspace Panel の Quit 操作で、ユーザー入力後に Panel の background reload / notice dispatch / snapshot load / Pod observation など非本質的処理待ちによる断続的な遅延が起きないよう、原因を特定して修正する。

Binding decisions / invariants:

  • Quit はユーザーの明示的な終了意思であり、Panel の観測/reload/通知送信完了待ちで遅延してはならない。
  • 端末状態復旧、描画 backend の正常終了、Rust drop による安全な abort など、最小限の終了処理は維持する。
  • Ticket lifecycle authority、Pod authority boundary、Panel row/action semantics、Companion/Orchestrator composer target semantics は変更しない。
  • resources/prompts や durable Ticket schema 変更は想定しない。必要になった場合は escalation。

Requirements / acceptance criteria:

  • Ctrl+C / Ctrl+D など現行 Quit 経路が pending background work によって目に見えて遅延しない。
  • 遅延原因と修正方針を implementation report に説明する。
  • 可能な範囲で unit test / regression test を追加し、Quit 経路が pending background work にブロックされないことを検証する。
  • 自動化が難しい場合は manual validation 手順と観測結果を report する。

Implementation latitude:

  • まず crates/tui/src/multi_pod.rs の event loop / PendingReload / Quit handling / terminal event polling / queue-attention notice dispatch / snapshot load を code-path spike する。
  • 修正手段は、不要 await の回避、cancellable background work の abort/drop、event-loop priority adjustment、test seam 追加などから Coder が選んでよい。
  • 再現が難しい場合は遅延し得る code path を単体再現できる test seam を優先してよい。

Escalate if:

  • Panel public UX、Ticket lifecycle semantics、Pod shutdown semantics、authority boundary の変更が必要になる。
  • 端末 cleanup や Pod process lifecycle safety を犠牲にしないと遅延を解消できない。
  • 原因が Panel 外（OS terminal / shell / external command / provider/network）にある証拠が出た。

Validation:

  • focused test for Quit not waiting on pending background work。
  • cargo fmt --check。
  • git diff --check。
  • 変更範囲に応じて cargo test -p tui ... / cargo check -p tui --all-targets。
  • 可能なら manual yoi panel Quit observation を report。

Current code map:

  • crates/tui/src/multi_pod.rs: Panel run loop、Quit key handling、PendingReload、background reload / attention notice / snapshot observation paths。
  • crates/tui/src/workspace_panel.rs: ViewModel は参照のみ。row/action semantics は変更しない。

Critical risks / reviewer focus:

  • Quit を速くするために terminal cleanup / safe abort / Pod lifecycle を壊していないこと。
  • nonessential background work が Quit を block しないこと。
  • Panel/Ticket/Pod authority semantics と row/action semantics が変わっていないこと。
  • Regression test が実際に pending background work block を防ぐ性質を持つこと。

State changed

Ticket evidence、relation records、existing OrchestrationPlan waiting/conflict notes、related completed Panel mouse integration、visible Pod/worktree state、and clean Orchestrator workspace were checked. The prior conflict/capacity blocker is resolved; no durable dependency blockers remain. Implementation can proceed in a dedicated child worktree with a first-step code-path spike and focused regression test before changing Quit behavior.

Implementation report

Implementation report for Ticket 00001KV0723PC

Commit: cfe411e50d (fix: avoid panel quit notice wait)

Observed / identified delay cause:

  • In crates/tui/src/multi_pod.rs, the workspace Panel run loop handled a completed PendingReload before polling terminal input.
  • When the reload result requested Orchestrator queue-attention notification, the loop awaited dispatch_orchestrator_queue_attention_notice(request) inline.
  • That dispatch path can wait on Unix socket connect/read/write operations and their timeouts. While it was awaited inline, queued terminal events such as Ctrl+C / Ctrl+D could not be observed, so an explicit Quit could be delayed by non-essential notice dispatch work.

Fix summary:

  • Added PendingQueueAttentionNotice, a cancellable background task wrapper for queue-attention notice dispatch.
  • Changed the Panel run loop to start queue-attention notice dispatch asynchronously after reload and only harvest the result when the task is already finished.
  • Added explicit quit cleanup through abort_panel_background_work_for_quit, aborting both pending reload and pending queue-attention notice work before returning MultiPodOutcome::Quit.
  • Also abort the background notice before foreground open/action paths that already abort reload work, so non-essential notice dispatch does not contend with user-directed operations.
  • Preserved terminal/backend shutdown behavior by keeping the existing return path and relying on explicit abort plus Rust Drop cleanup for background tasks.

Files changed:

  • crates/tui/src/multi_pod.rs

Regression coverage:

  • Added multi_quit_aborts_background_reload_and_notice_without_waiting, which starts never-completing reload and notice tasks, exercises the quit abort helper under a timeout, and verifies both tasks are cancelled.
  • Existing reload overlap behavior remains covered by multi_poll_reload_does_not_overlap_in_flight_reload.

Validation commands/results:

  • cargo fmt --check — passed
  • git diff --check — passed
  • cargo test -p tui multi_quit_aborts_background_reload_and_notice_without_waiting --lib — passed
  • cargo test -p tui multi_poll_reload_does_not_overlap_in_flight_reload --lib — passed
  • cargo check -p tui --all-targets — passed

Residual risks / manual validation notes:

  • No broad runtime-loop rewrite was done. Foreground user-directed operations that are already awaited by the Panel can still occupy the loop; this change targets the identified non-essential background notice dispatch delay path.
  • I did not run an interactive manual yoi panel session from this Coder environment. Recommended manual check: start yoi panel, trigger a reload/queued Ticket condition that would dispatch queue-attention notice, then press Ctrl+C/Ctrl+D while the notice target is slow or unavailable; the Panel should exit promptly while terminal state is restored.

Review: approve

Review: approve

Evidence:

  • Reviewed Ticket intent/criteria and git diff 9dacc90e..HEAD for commits cfe411e5 and 8de82836.
  • The reported delay cause is plausible in the previous loop shape: a completed reload was processed before input polling and could inline-await queue-attention notice dispatch; that dispatch uses Pod socket connect/read/write paths, so queued Ctrl+C / Ctrl+D input could wait behind nonessential notice work.
  • The implementation changes only crates/tui/src/multi_pod.rs plus the implementation report. Queue-attention notice dispatch is now wrapped in a cancellable PendingQueueAttentionNotice, started in the background, and harvested only after completion. Reload dispatch is guarded against overlap.
  • Quit handling now calls abort_panel_background_work_for_quit, aborting pending reload and pending queue-attention notice tasks before returning the existing MultiPodOutcome::Quit; this keeps the established terminal/backend cleanup return path intact.
  • Existing foreground open/action helper paths also abort the nonessential pending notice before returning user-directed outcomes, so stale notice dispatch does not block those paths.
  • No Ticket lifecycle authority, Pod authority boundary, Panel row/action semantics, composer target semantics, prompt resources, or Ticket schema changes were introduced.
  • The regression test starts never-completing reload and notice futures, exercises the quit abort helper under a timeout, and verifies cancellation of both tasks. This is a meaningful regression for the pending-background-work latency path rather than only checking that a helper was wired.

Validation performed:

  • cargo test -p tui multi_quit_aborts_background_reload_and_notice_without_waiting --lib — passed.
  • cargo test -p tui multi_poll_reload_does_not_overlap_in_flight_reload --lib — passed.
  • cargo fmt --check — passed.
  • git diff --check — passed.
  • cargo check -p tui --all-targets — passed.

Risks / notes:

  • I did not run an interactive yoi panel manual latency check. The code-path review and focused tests cover the identified nonessential reload/notice wait path.

Implementation report

Integration outcome: merged and validated.

  • Implementation branch: ticket-00001KV0723PC-panel-quit-latency
  • Implementation commits: cfe411e5 fix: avoid panel quit notice wait, 8de82836 ticket: report panel quit latency fix
  • Review commit: 2bb36cc4 ticket: approve panel quit latency
  • Orchestrator merge commit: db7bad7a merge: panel quit latency

Reviewer result:

  • approve。旧経路で reload 完了後に queue-attention notice dispatch を inline await していたことが Quit 遅延原因として妥当であること、実装が background/cancellable 化と Quit abort cleanup で解消していること、terminal/backend cleanup path と authority semantics を維持していることを確認済み。

Orchestrator validation after merge:

  • cargo test -p tui multi_quit_aborts_background_reload_and_notice_without_waiting --lib: PASS
  • cargo test -p tui multi_poll_reload_does_not_overlap_in_flight_reload --lib: PASS
  • cargo fmt --check: PASS
  • git diff --check: PASS
  • cargo check -p tui --all-targets: PASS

Residual notes:

  • Interactive yoi panel manual latency check は未実施。ただし、code-path review と focused tests で特定された nonessential reload/notice wait path は cover されている。
  • Ticket lifecycle authority、Pod authority boundary、Panel row/action semantics、composer target semantics、prompt resources、Ticket schema は変更していない。

Next:

  • Ticket を done に遷移し、panel quit child Pods / worktree / branch を cleanup する。close は別途明示権限がある場合に行う。

State changed

Implementation branch ticket-00001KV0723PC-panel-quit-latency was reviewed, approved, merged into the Orchestrator branch as db7bad7a, and validated in the Orchestrator worktree. Focused panel quit latency tests, formatting, diff check, and cargo check -p tui --all-targets passed. Ticket implementation work is done; closure remains separate.
